Since the label includes the label and the sticker after printing, the adhesive layer of the label is located on the side of the label close to the sticker, and the label is separated from the sticker by the simultaneous adsorption of the third adsorbing member 538 and the fourth adsorbing member 547, and the label is adsorbed by the fourth adsorbing member 547.The output mechanism 51 can be regarded as a conveyor belt. The transfer component 2 can move the screen that has not passed the inspection to the output mechanism 51, and then the labeling mechanism 54 sticks the label to the screen that has not passed the inspection, and then the output mechanism 51 drives the screen that has not passed the inspection to move to the outside.

[0041] Preferably, it also includes a re-inspection loading component 61, which has the same structure as the loading component 1. The screen that fails the inspection is manually repaired and passed the manual inspection, and then placed on the re-inspection loading component 61. The transfer component 2 drives the re-inspected screen through the first adsorption component 24 to complete the unloading.

[0042] Preferably, the loading component 1, the transfer component 2, the conveying component 3, the detection component 4, the feeding component 5 and the re-judgment loading component 61 are all connected to the base, so that the above components can be stably fixed.

[0043] When in use, the screen to be detected is placed on the first movable platform 12, and the first driving member 11 drives the screen to be detected to move to the detection position of the first detection member 13 for alignment, so that the first adsorption member 24 of the transfer component 2 can accurately adsorb the screen to be detected, and then the second driving member 22 and the third driving member 23 of the transfer component 2 cooperate to drive the first adsorption member 24 to adsorb the screen to be detected and transfer it to the second movable platform of the conveying component 3, and the screen to be detected can be accurately placed in the card slot 332 of the second movable platform 33 through the alignment of the first detection member 13, and then the fourth driving member 32 drives the second movable platform 33 to move to the manual operation position, and after the connector 334 is manually connected to the screen to be detected, the fourth driving member 32 drives the second movable platform 33 to move to the detection position of the detection component 4, and the first light source member 41, the second light source member 42, the second detection member 45, the third detection member 48, and the fourth detection member cooperate with each other to make the second detection member 45 and the third detection member 48 move to the detection position of the detection component 4. 48 can inspect the screen to be inspected. After the inspection is completed, the fourth driving member 32 drives the inspected screen to move to the manual operation position again, and the connector 334 is manually disconnected from the inspected screen. Then the fourth driving member 32 drives the inspected screen to move to a position where the transfer component 2 can adsorb. If the inspection passes, the transfer component 2 drives the inspected screen to move to the next workstation. If the inspection fails, the transfer component 2 drives the screen that fails the inspection to move to the output mechanism 51, and then the labeling mechanism 54 sticks the label to the screen that fails the inspection. The output mechanism 51 then drives the screen that fails the inspection to move to the outside for manual repair and re-inspection. After the screen that fails the inspection is manually repaired and re-inspected, it is placed on the re-inspection loading component 61 as a re-inspection screen. The re-inspection loading component 61 drives the re-inspection screen to move to a position where the transfer component 2 can adsorb. The transfer component 2 drives the re-inspected screen to move to the next workstation through the first adsorption member 24.

[0044] In the screen defect detection device of the present embodiment, the loading component 1 and the transfer component 2 cooperate to drive the screen to be detected to move to the second moving platform 33 and position it, and then the conveying component 3 drives the screen to be detected to the detection component 4 for detection. The detection and positioning process does not require manual positioning and installation, thereby preventing the screen from being damaged during the detection process and improving the accuracy of the detection results. By setting the feeding component 5 and the re-judgment loading component 61, the screen that has not passed the detection is manually repaired and re-tested, and the transfer component 2 drives the re-judged screen to enter the production line, thereby improving the discharge efficiency.

[0045] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
